When I am cruising on the highway at a constant speed, the rpm's will sometimes jump a few hundred and I can hear the engine rev. The truck doesn't accelerate and I am not pushing down on the gas pedal. Could this be a sensor issue or a torque converter issue? The truck idles smoothly, and shifts gears smoothly. Any other things that could be causing this?
